Title: Method for controlling gain of reception wave in measuring device using ultrasonic wave
Inventor: ARAI SATOSHI
IPC: G01S7/529
Filed: 1994-12-02
Abstract: PURPOSE: To prevent the deviation of reference wave and enable accurate measuring by controlling the amplitude degree so that the peak value of a wave in a reverse amplitude direction just before the reference wave may become a threshold value. CONSTITUTION: An waveform inversion amplifier 5 inverts output signal of a gain control amplifier 3 and outputs the inverted signal to a peak hold circuit 6. The circuit 6 specifies a reference wave P1 which exceeds a threshold value S in one amplifying direction firstly, out of respective waves of the output signals from the amplifier 3. At the same time, a peak value of an index wave P0.5 in the other amplifying direction just before it follows the wave P1 is detected based on the output signal from the amplifier 5, and an auto gain control signal is generated based on the peak value of the index wave P0.5 . The generated signal is outputted to the amplifier 3, and the amplifier 3 amplifies an output signal of a wave reception device 2 at such a amplitude degree that the peak value of the index wave P0.5 may coincide with the threshold value S, based on the outputted signal.  Thus, a wave P0 just before the index wave P0.5 hardly exceeds the threshold value S, and the deviation of the reference wave P1 can be prevented, resulting in accurate measurement.

Title: Restoration of hydrogen permeability of hydrogen separation membrane
Inventor: KOBUCHI AKIRA
IPC: B01D53/22
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To reduce energy loss and simplify an apparatus in restoring the permeability of a paladium-based hydrogen separation membrane having hydrogen permeability lowered by keeping the temperature of a paladium-based hydrogen separation membrane apparatus at the hydrogen-separation operation temperature or higher and by causing steam to flow through the before-permeation side. SOLUTION: In producing high-purity hydrogen, a feed gas introduction valve 14 and a steam introduction valve 15 are opened to supply the raw material and steam to a steam reforming apparatus 10. In this apparatus 10, the raw material is reacted with steam to produce a hydrogen-containing gas, which is supplied to a hydrogen separation membrane apparatus 1. In restoring the permeability of a hydrogen separation membrane having hydrogen permeability lowered, the feed gas introduction valve is closed while the steam introduction valve 15 is kept open, thus reducing the pressures of the steam reforming apparatus 10 and the hydrogen separation membrane apparatus 1 to the atmospheric pressure.  The permeability can also be restored by causing steam to flow through the beforepermeation side of the hydrogen separation membrane apparatus 1 while the temperature of the apparatus 1 is kept at 200-600 deg.C.

Abstract: PURPOSE:To enable stable transmission through a space directly without requiring any transmission medium such as an optical fiber or the like by transmitting input data information as data information in a transmission format when an address is coincident, and preventing the data information from being transmitted at least when the address is not coincident. CONSTITUTION:A receiving signal (a) is converted to parallel address information (c) by an address part serial/parallel converter 2 and compared with an address set by a set switch 4 by an address information comparator 5 and when the address is not coincident, a transmission changeover switch 8 is changed over to a terminal 2. When the address is coincident, the transmission changeover switch 8 is changed over to a terminal 3, and the data information is replaced with information serially converting the parallel input data by a data part parallel/serial converter 6. Only when the address of a slave station 11 is not overlapped, a master station 10 receives only the signal from an accessed slave station 11a, and the signal can be received without being interfered by the other slave station 11. Thus, stable communication is enabled.

Abstract: PROBLEM TO BE SOLVED: To enable change of tone color without changing the shape of musical sound waveform signals by changing the phase of the musical sound waveform signals generated repeatedly, and enable the musical sound waveform signals changed in its phase to be switched from the musical sound waveform signals generated repeatedly and outputted continuously. SOLUTION: In a musical sound signal generation unit 5, musical sound waveform signals having a specified length are generated repeatedly and outputted from a surround system 6.
